Description

Technical Field

[0001] The utility model belongs to the technical field of surface grinders, and particularly relates to a hatch structure of a surface grinder. Background Art

[0002] A surface grinder is a type of grinding machine that mainly uses a grinding wheel to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable surface grinder are the worktable width and length, and the main parameter of a circular worktable is the worktable diameter. According to the type of shaft, it can be divided into horizontal shaft and vertical shaft grinders.

[0003] The hatch of a surface grinder generally slides via pulleys and guide rails, but the existing hatch of a surface grinder does not have a buffer structure. When the hatch is opened to both sides, it is easy for the hatch to collide with the inner wall of the grinder, causing damage to the inner wall of the grinder or the hatch, which reduces the durability of the surface grinder. In addition, when the grinder is working, it is easy for debris to be ejected in all directions. The debris directly hits the observation window, which can easily cause damage to the observation window. Therefore, we propose a hatch structure for a surface grinder. Utility Model Content

When the protective door 3 is opened to both sides, the protective door 3 moves with the pulley 2 in the slide groove. When the protective door 3 approaches the inner wall of the grinder housing 1, the extrusion plate 2 88 first contacts the inner wall of the grinder housing 1, and the extrusion plate 2 88 transmits the impact force to the buffer spring 83 through the extrusion plate 1 84, avoiding direct contact between the protective door 3 and the inner wall of the grinder housing 1, preventing the protective door 3 from colliding with each other and causing damage to the inner wall of the grinder or the protective door 3. By adjusting the position of the adjusting nut 1 86, the extrusion plate 1 84 and the adjusting nut 2 87 on the threaded rod 85, the maximum moving stroke of the extrusion plate 2 88 can be changed. The buffer cylinders on both sides of the extrusion plate 2 88 further reduce the impact force. A protective plate 6 is provided. The protective plate 6 is made of a transparent acrylic plate and is fixed to the inner side of the protective door 3 by bolts, covering the outside of the observation window 5 to protect the observation window 5 and prevent the debris splashed during operation from directly rubbing against the observation window 5. The bolt fixing also makes it easy to replace the protective plate 6.

[0024] Furthermore, the pulley 2 is T-shaped, and the pulley 2 includes a connecting rod and a wheel. The inner wall of the slide groove and the wheel surface of the pulley 2 fit each other. The pulley 2 and the slide groove cooperate to drive the protective door 3 to move, thereby realizing the opening and closing of the protective door 3.

[0025] Furthermore, a thread groove 1 is provided on the surface of the protective door 3 and the protective plate 6. The protective plate 6 is installed on the surface of the protective door 3 close to the inner side of the grinder housing 1 by means of bolts and the thread groove 1.

[0026] Furthermore, the fixed seat 81 is fixedly connected to the surface of the protective door 3 close to the side wall of the grinder housing 1, and four groups of limit plates 82 are arranged around the circumference. The four groups of limit plates 82 constitute a group of hollow cylindrical structures. When the surface of the extrusion plate 2 88 contacts the surface of the limit plate 82, the maximum moving distance of the extrusion plate 2 88 is reached.

By adjusting the positions of the adjusting nut 1 86, the extrusion plate 1 84 and the adjusting nut 2 87 on the threaded rod 85, the maximum movement stroke of the extrusion plate 2 88 can be changed.

[0029] Furthermore, the radius of the second extrusion plate 88 is larger than the radius of the hollow cylindrical structure formed by the four groups of limit plates 82. Multiple groups of buffer cylinders are provided on both side surfaces of the second extrusion plate 88, and the buffer cylinders further reduce the impact force on the buffer structure 8.

[0030] Working principle: When in use, the protective door 3 is opened to both sides by the handle 4. The protective door 3 moves along with the pulley 2 in the slide groove. When the protective door 3 approaches the inner wall of the grinder housing 1, the extrusion plate 2 88 first contacts the inner wall of the grinder housing 1. The extrusion plate 2 88 transmits the impact force through the extrusion plate 1 84 to the cushioning spring 83, avoiding direct contact between the protective door 3 and the inner wall of the grinder housing 1, preventing the protective door 3 from colliding with the inner wall of the grinder, causing damage to the inner wall of the grinder or the protective door 3. By adjusting the adjusting nut 1 8 6. The positions of the extrusion plate 1 84 and the adjusting nut 2 87 on the threaded rod 85 are used to change the maximum movement stroke of the extrusion plate 2 88. The buffer cylinders on both sides of the extrusion plate 2 88 further reduce the impact force. The material is placed on the grinder body 7 for operation. When the grinder is working, it is easy to eject debris all around. A protective plate 6 is fixed on the inner side of the protective door 3 by bolts to protect the observation window 5 and prevent the flying debris from directly rubbing against the observation window 5 during operation.
